title: Benign glomus tumor of the urinary bladder.
abstract: Glomus tumors are rare, mesenchymal neoplasms of adulthood, which occur in both the sexes with equal frequency. Most of these tumors are benign, but some cases with atypical/malignant behavior have been reported. They most often occur in the extremities, typically in the subungual region of the fingers, and rarely involve the internal organs. We report the case of a 63-year-old man who presented with hematuria. The cystoscopy showed a polypoid lesion of the anterior wall of the bladder, which was diagnosed on biopsy as a benign glomus tumor. To the best of our knowledge, this is the first case of benign glomus tumor of the bladder described in the literature. This report widens the spectrum of the differential diagnoses of bladder neoplasms.
